Ivylog and Executive. Thanks for the replies. I wonder if an oscillating fan held on with duck tape would get me a " you are a redneck" card? Although my test was far from scientific it just emphasized what others have been saying. You need lots of air flows. I wonder what would have happened if Norcold had engineered some high tech fans into the fridge when manufactured. Maybe the CUY's would last longer? I checked again this morning and both boxes were about 3 to 4 degrees colder. But as Ivylog noted not even. But the fridge is empty. I would think that cold items would act as a cold sink to make more even temps? Do not know when I will get the roof fans installed but I have a small computer fan I might set behind the vent door to see what happens. I wish Norcold was paying me by the hour!
